4 Claims.

The present invention relates to new and useful improvements in casing pullers and cable guides for well drilling machines and has for one of its important objects to provide, in a manner as hereinafter set forth, a device of this character comprising a novel construction and arrangement whereby a casing or drive pipe may be expeditiously pulled without the necessity of removing the drilling tool from the cable.

Another very important object of the inven tion is to provide a casing puller and cable guide of the aforementioned character embodying a unique construction whereby the device may be be conveniently mounted on the cable and connected to the casing.

Still another important object of the invention is to provide a puller and guide of the character described which is adapted for connection to different sizes of casings or drive pipes.

A still further important object of the invention is to provide a device of the aforementioned character which, when used as a guide, will prevent the cable from ".whipping? Other objects of the invention are to provide a casing puller and cable guide of the character set forth which will be comparatively simple in construction, strong, durable, highly efiicient and reliable in use, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specication, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts through- "out the several views, and wherein:

Figure 1 is an elevational view of a casing pu ler and cable guide constructed in acccordance with the present invention, showing the device installed and ready for use.

Figure 2 is a top plan View of the device.

Figure 3 is a view in vertical section through the device.

Referring now to the drawing in detail, it will be seen that the embodiment of the invention which has been illustrated comprises what may be referred to as a plug of any suitable metal which is designated generally by the reference numeral I. The plug l includes a smooth, cylindrical upper end portion 2 beneath which are formed successively reduced, threaded portions 3 and 4. Further, the plug l terminates in a reduced, smooth lower end portion 5.

The reference numeral 6 designates a section of casing on the upper end portion of which. .1 a coupling 1. L casing 6 is a cable 8 having mounted on its lower end portion a drilling toolQ. The portion 3 of the plug I is adapted to screw into the coupling 1 thereby firmly connecting said plug to the casing ii. It may be well to here state that the portion 4 of the plug l is adapted to screw into casings of smaller diameter than that which has been illustrated. The lower end portion 5 of the plug l is adapted to fit into the smaller size casings;

- Formed vertically in the plug 5 and extending from end to end thereof is a groove or channel Iii. In depth, the groove lil extends from the periphery of the plug l to the central portion thereof. The groove l0 slidably receives the cable 8. I

Threadedly mounted in the upper portion 2 of the plug l is a removable bolt H which traverses the groove Ill. A threaded bore l2 in the plug l accommodates the bolt II. A recess IS in the upper portion of the plug l accommodates the head M of the bolt H. The bolt ll constitutes a pin on which a peripherally grooved guide roller i5 is journaled in the upper portion of the groove l0.

Extending into the upper potrion 2 of the lug l is a socket It for the reception of a lever or handle to facilitate screwing said plug into or out of the coupling. Mounted on the upper end of the plug I is an eye bolt I! to which a sand line maybe conveniently connected to facilitate hoisting the device and screwing it into the casing.

It is thought that the manner in which the device functions will be readily apparent from a consideration of the foregoing. Briefly, the

Extending downwardly into if bolt I! and the roller 15 are removed to permit the plug l to he slipped on the cable 8 and screwed into the coupling 1. The cable 3 and the tool 9 are then utilized to pull the casing,

said tool striking the lower end l8 of the plug i.

readily understood and although a preferred embodiment of the device is as illustrated and described, itis to be understood that changes in the details of construction and in the combination and arrangement of parts, maybe re u sorted to which will fall within the scope of the invention as claimed.

What is claimed is:

1. A casing puller and cable guide comprising a plug including means for connection with a casing, said plug having a vertical groove therein for the reception of a cable.

2. A casing puller and cable guide comprising a plug for connection with a casing, said plug having a vertical groove therein for the reception of a cable, and a retaining roller for the cable journaled in the groove.

3. A casing puller and cable guide comprising a plug including a threaded portion for connection with a casing, said plug having a vertical groove therein for the reception of a cable, a removable pin mounted in the plug and traversing the groove, and a retaining roller for the cable journaled on said pin in the groove.

4. A casing puller and cable guide comprising a plug including. a reduced, threaded intermediate portion adapted to be screwed into a casing, said plug terminating in a further reduced lower end portion adapted for insertion in the casing,- said plug having a groove extending vertically therethrough for the reception of a cable, and a removable retaining roller for the cable journaled in the groove.
